My Lexus has tires that came with the car - Uhh... Not a famous brand. Ironman Imove. But I left them because the online ratings are decent. In dry and wet they are fine. They seem pretty hard and have no sipes (like the LTX for example on my explorer) When the snow started falling, I tested things out on streets with no traffic, and was able to slide thru stopsign intersections with pretty good stopping distance. (Again, no cars, anywhere, suburban dead end streets). Now, I want to blame the tires but, is toyota ABS too aggressive in the snow? Also, it is an AWD car with full time center planetary diff, that can lock up, but I'm not really impressed. I wonder if tires can make such a difference.
